Verifying zeros using a 4-wire short
Check the zeros of various test points while the 4-wire is connected to the
Series 3700 analog backplane connector and verify that the displayed readings
fall within specified limits.
CAUTION Do not exceed 300V peak between INPUT HI and INPUT LO
because instrument damage may occur.
To verify DC voltage and resistance zeros:
1. Select the DC volts function.
2. Set the Series 3700 to the 100mV range.
3. Connect the 4-wire short to the Series 3700 analog backplane connector
and allow to settle for 5 minutes (do not use REL).
4. Verify the 100mV zero is within specification (see the 4-wire short applied
verification data (on page 14-26) table).
5. Set the Series 3700 to the 1V range.
6. Allow to settle for 30 seconds (do not use REL).
7. Verify the 1V zero is within specification (see the 4-wire short applied
verification data (on page 14-26) table).
